Dmitrij [34]
The ocean absorbs CO2 from the atmosphere wherever air meets water. Wind causes waves, giving more opportunity for the water to absorb the carbon dioxide.

Methanol can be produced by the following reaction: CO(g) 2 H2(g) CH3OH(g). How is the rate of disappearance of hydrogen gas rel
belka [17]

Answer:

r_{H_2}=-2r_{CH_3OH}

Explanation:

Hello!

In this case, for the reaction:

CO(g)+ 2 H_2(g) \rightarrow CH_3OH(g)

In such a way, via the rate proportions, that is written considering the stoichiometric coefficients, we obtain:

\frac{1}{-1} r_{CO}=\frac{1}{-2} r_{H_2}=\frac{1}{1} r_{CH_3OH}

Whereas the reactants, CO and H2 have negative stoichiometric coefficients; therefore the rate of disappearance of hydrogen gas is related to the rate of appearance of methanol as shown below:

\frac{1}{-2} r_{H_2}=\frac{1}{1} r_{CH_3OH}\\\\r_{H_2}=\frac{-2}{1} r_{CH_3OH}\\\\r_{H_2}=-2r_{CH_3OH}

Which means that the rate of disappearance of hydrogen gas is negative and the rate of appearance of methanol is positive.

Regards!

The system will adjust itself in order to resist the change.

Explanation:

  • Frenchman Le Chatelier in 1888 is credited with the Le Chatelier's principle
  • His principle is a summary drawn from his findings on various factors that affects equilibrium.
  • The principle states that "if any of the conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".
  • It is used to explain the effect of stress by applying change on a system.
  • The changing conditions are usually concentration, temperature and pressure.
